Title: Capillary for wire bonding
Inventor: MIURA HIROYUKI
IPC: H01L21/60
Filed: 1986-02-28
Abstract: PURPOSE:To inhibit the adhesion of a conductor and electrode powder, to improve hardness, abrasion resistance and heat-dissipating characteristics and to lengthen life by forming at least a nose section in a capillary by specific polycrystalline ceramics. CONSTITUTION:At least a nose section in a capillary 1 for wire bonding is shaped by alumina polycrystalline ceramics having purity of 99.9% or more and a mean pore diameter of 1mum or less. Consequently, the defective connection of a wire is difficult to be generated because a conductor and electrode powder to the nose section hardly adhere on the nose section, and the breaking and abrasion of the nose are reduced and life is lengthened because strength and abrasion resistance are increased and heat-dissipating characteristics are improved. The wires can be bonded stably, thus stabilizing the quality of a semiconductor device.

Title: Control device for lock-up clutch
Inventor: MORI KIYOUSUKE
IPC: F16H61/14
Filed: 1990-02-26
Abstract: PURPOSE:To control the differential pressure with a higher degree of accuracy by providing a lock-up reducing valve so that a hydraulic pressure regulated at a predetermined value is applied to a lock-up control valve when the solenoid pressure is higher than the predetermined pressure. CONSTITUTION:The solenoid pressure given by a lock-up solenoid 58 is applied directly to a lock-up control valve 32 when the solenoid pressure is around a predetermined value. However, a hydraulic pressure regulated at the predetermined value by the lock-up reducing valve 80 is applied to the lock-up control valve 32 when the solenoid pressure is higher than a predetermined value. With this arrangement, the degree of influence by the solenoid pressure upon the pressure regulated condition of the lock-up control valve 32 becomes low, and accordingly a differential pressure adapted to act upon a lock-up clutch 18 in a torque converter 10 can be controlled more precisely. Further, by changing the above-mentioned predetermined value in accordance with a hydraulic pressure in a supply chamber, it is possible to control the differential pressure always at a desired value.

Abstract: PURPOSE:To prevent shocks upon speed change by smoothly fastening a second friction element for low speed stage selection by a predetermined time corresponding to a play in the second friction element, and by compensating this predetermined time in accordance with the rotating condition of a speed change gear input shaft. CONSTITUTION:When hydraulic pressure is fed from a 2-3 shift valve 103 to both actuators 101, 102 for first and second friction elements 16, 19, a first shift stage is selected. When the hydraulic pressure is released from both actuators, a low speed second shift stage is selected. In this arrangement the release of hydraulic pressure from the second actuator 102 or the fastening of the second friction element which causes shocks upon gear shift, is desired to be smoothly carried out by a predetermined time in consideration with a play in the second friction element, and therefore, a control circuit 200 controls a timing valve 104 to promote the release of the hydraulic pressure, and upon complete fastening, the fastening is carried out gradually by means of a restrictor orifice 108 alone. Further, the above-mentioned predetermined time is compensated to an optimum value in accordance with the gear shift condition based upon the rotation of a speed change gear input shaft 161 Thus, it is possible to reduce shocks upon gear shift.

Abstract: PURPOSE: To improve the luminous efficiency of a cold cathode fluorescent lamp to realize high efficiency, high brightness, miniaturization, light weight, and less power consumption, by appropriately setting the inner diameter of the cold cathode fluorescent lamp within a given dimensional range, and also appropriately setting the lighting frequency of the cold cathode fluorescent lamp within a given frequency range. CONSTITUTION: When a fluorescent lamp, having a tube length of 150mm, a thickness of 0.5mm and an inner diameter of 2.0mm, is lit at a frequency of 38kHz; the reference luminous efficiency of a cold cathode fluorescent lamp 7 is made 100. When a lighting frequency becomes 60kHz or higher, an inner diameter, having efficiency higher than the reference luminance efficiency of 100 in the range of examined inner diameters of 0.5-1.8mm, appears; and when a lighting frequency becomes 80kHz or higher, the luminous efficiency becomes higher than 100 in all inner diameters of examined diameters of 0.5-1.8mm, and this fluorescence continues to 160kHz. Since electric effect such as noise generation is increased at a frequency of 160kHz or higher, this frequency is not adopted.  When an inner diameter has 1.8mm or larger, the luminous efficiency of the lamp 7 becomes only slightly higher than the reference luminous efficiency of 100, and reversely a luminous efficiency of 100 or higher, wherein an inner diameter becomes 1.8mm or smaller, can be stably obtained. An inner diameter of 1.8mm or larger and 0.5mm or smaller is not adopted from the viewpoint of manufacture.
